Multiquip 7812036404 Air Cleaner Hose TLW300SS

The Multiquip 7812036404 Air Cleaner Hose TLW300SS is a genuine OEM component designed for DLW300ES series diesel light welders. As a factory-sourced part, 7812036404 is manufactured to the same specification as the original, ensuring a direct connection between the air cleaner assembly and the engine intake without improvisation or adaptation. This hose is confirmed for DLW300ES, DLW300ESA, and DLW300ESA1 models, making it the correct choice when servicing these units.

Key Features

• Genuine OEM Construction — Produced to original material and dimensional specifications, ensuring the hose maintains proper airflow sealing under the operating conditions of the DLW300ES welder engine.
• Direct Bolt-On Replacement — Matches the original routing, connection diameter, and mounting points, so installation follows the same procedure as the factory unit with no rework required.
• Confirmed Fitment — Verified for DLW300ES, DLW300ESA, and DLW300ESA1 diesel light welder models in the Multiquip lineup.
• Protects Engine Air Supply — A properly seated air cleaner hose keeps the intake path sealed, preventing unfiltered air from bypassing the air cleaner and reaching the engine.
• Correct Part Number Verification — Sourced directly under Multiquip part number 7812036404, eliminating guesswork when ordering a service replacement.

The air cleaner hose connects the air cleaner housing to the engine's intake, channeling filtered air into the combustion system. A cracked, collapsed, or poorly seated hose allows unfiltered air to enter the engine, which accelerates internal wear and can cause rough running or loss of power over time. On a diesel light welder like the DLW300ES series, where consistent engine performance directly affects welding output quality, keeping this connection intact is a routine but critical part of ongoing maintenance.
